Abstract (en)
[origin: WO9839509A1] Improved sheets of bonded plexifilamentary film-fibril strands spun from a polyolefin and a pigment are provided. The polyolefin comprises at least 90 % by weight of the fibril strands, and the pigment comprises between 0.05 % and 10 % by weight of the fibril strands. The sheet has a high opacity, even when the sheet is bonded to a delamination strength greater than 120 N/m. The pigment in the sheet may be titanium dioxide, a black pigment or a colored pigment.
